SANITARY MOUTH? IECE COVER Filed Aug 8, 1955 Patented Sept. 22, 1936 UNITED STATES PATENT OFFICE SANITARY MOUTHPIECE COVER Godel Kalenofi, Brooklyn, N. Y.

Application August 8, 1933, Serial No; 684,160

1 Claim. (01. 179-185) This invention relates to a novel and improved cover for the mouthpieces of telephonic transmitters, and it is the principal objector my invention to provide a sanitarycover which is readily 5 attached to and removed from a mouthpiece and will prevent the spread of contagious diseases.

Another object of my invention is the provision of a sanitary cover for the mouthpieces of telephonic transmitters of simple, and inexpensive 10 make, however highly efiicient in use and which when engaged with the mouthpiece is safely held to the same, while it may be readily removed after use, so that every person using the telephone may quickly attach a new cover to the same prevent- 15 ing the spreading of disease.

A further object of my invention is the provision of a cover for the mouthpieces of telephonic transmitters made of any suitable material readily formed from suitable blanks and either ready made or to be easily prepared by the user of the telephone from the blanks.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds and will then 5 be more specifically defined in the appended claim.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 shows the preferred form of my cover. 30 Fig. 2 illustrates part of the blanks from which my cover, Figure 1 is formed.

Fig. 3 shows another modified form of cover according to my invention.

Fig. 4 illustrates a blank from which the cover,

35 Figure 3 is formed.

As illustrated on the drawing, Figures 1 and 2 the body 22 is formed from a suitable blank the material of which is doubled upon itself, as at 23, 24 and tongues 25, 26 struck out from the 40 upper margin forming recess 21 overlap and hold the overlapping cover parts together in form of a cone to be inserted into the telephone mouthpiece. Inuse the blank is doubled upon itself, and the tongues at the upper margin are bent 45 upon themselves to overlap and thushold the overlapping cover parts together in the shape of a cone adapted to be conveniently inserted into the telephone mouthpiece.

In the form of my invention illustrated in 5 Figures 3 and 4, the cover is formed from a blank 52 of the form illustrated having a median recess 53 formed in its inner margin, while a wire 54 is embedded in the rolled up material of the outer margin 55, so that the ends of the wire engage when the cover is formed with the ends of the material at the margin of the blank united. If desired, the ends of the wire 54 may be hookshaped to ensure a secure engagement and hold of the body when formed. In the form of blank illustrated in Figures 3 and 4 bendable tongues 25 and 26 are provided at the edge of the blank which forms the smaller opening in the truncated conical device when formed, and these tongues when together are bent backward upon themselves to secure the blank in proper shape for use. Thus in both forms of the invention 11- 15 lustrated I provide means at the smaller end of the truncated conical device for holding the same in proper formation for use.

In use the wire is embedded into the tunnel formed by rolling up the material of the margin and the body is formed in the customary manner and held in shape by the engaging wire ends after being placed into the telephone mouthpiece.

It will be understood that I have disclosed a few of the many possible forms of my invention as examples only, and that I may make such changes in their form and in the construction of the minor details thereof, as come within the scope of the appended claim without departure from the spirit of my invention and the principles involved.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

A sanitary mouthpiece cover, consisting of a flexible sheet blank formed with a radial outer edge doubled upon itself to provide a reinforcing rim of tubular construction, said blank being formed into a cone to provide overlapping edge portions, the cone having an open smaller end 40 providing a voice opening, a metal ring disposed in the tubular rim and having end portions adapted to bridge the gap between the overlapping edge portions to prevent collapse of the cone at its larger end, said blank being further formed with malleable lugs foldable over said edge portions to retain the cone in formed condition to adapt it to fit snugly within the conical mouthpiece of a telephone transmitter.
